Yes, I have held many grudges before for a few years, but eventually I just forget it or I no longer feel the grudge because it has been so long...

I would forgive people very quickly if it is for something trivial or if they apologize to me. But if it's something I feel is big enough (by that, I mean it is enough to have an actual negative effect in my life), then I might hold the grudge for a few years unless I forget it. (But normally I tend to forget it in less than a year but occasionally I remember it so I guess I wouldn't say my grudge is gone)

But yea, holding grudges can be silly. I don't think it would help me in any way. It will only just bother me so I try my best to just forget about it. An example of some grudges I hold was when many classmates used to bully me back in elementary school. But towards middle school, I had a growth spurt and now everyone is afraid to mess with me. Another one was from teachers that were terrible and just like biased bullies as well... 

Another one was from another guy who did something to my parents. I feel like this one was the worst. But everything has been fine now but I don't want to go into detail. Just remembering it is.... UGH. 

But ehh... I feel like I have pretty much hold no more grudges now. 

There are many times where I held on to my anger towards somebody, mostly little things that easily made me upset. My sister and I never got along for many years because we felt like we couldn't forgive each other for the things we said to each other.

Also, it's hard not to hold a grudge when friends of mine don't respond to me, or they seem to be just losing interest in me. That happens to everybody but for a long time I had no idea how to handle it. :/ I've learned to let go of friendships that feel one-sided or don't feel genuine, so I'm more relieved and less mad. But I struggle not to feel that way when I keep seeing those former friends, especially if they're talking to other friends of mine.

I don't hold grudges. I do relish my revenge though.

When I prove somebody wrong, show them, that I could do something that they thought I couldn't, or I escaped their manipulative trap? I stand up tall and laugh. For all my low self esteem and realistic outlook upon life. . . I can briefly act like quite an egomaniac and just. . . not stop.

I don't actively relish my grudges, in fact, I don't have them.

But when I come out on top. When I've proved something. When I've reclaimed my honor? I relish it. I enjoy it. I love it, and I will take full occupation as the new ruler on the block.

It's complicated, but no, I don't hold onto things. I do use my angst and desire to make things better to keep myself moving forward though. We as humans experience emotion for a reason. The thing is, you don't dwell on them all the time. Let it take it's place, and don't become too obsessed. Hate, and angst can be powerful tools at your disposal, but like most of life, you need logic to guide you too.

I have mastered my anger. It is one of my most powerful tools when boiling deep down inside. A fuel that keeps on going, and I don't make life miserable on other people either. In fact I am genuinely happy most of my life, and I enjoy people's company. But when the time comes, the angst and the reminder is always there. It is the steady fuel that allows me to create. The other half of the time, I am creating out of love. A love for what should, could and would be, if only I could be there.

And then there is sadness, and equally powerful emotion. An emotion that doesn't create like love and hate can, but can create very small, fine and impacting points.

An author knows about all of his emotions. And they are the lifeblood of himself. ^^
