is personality consistent?

I would argue that what you want to do informs and reflects your personality much more than your personality informs what you want to do. Personality - the thing that makes you distinctly you - isn't static. As your wants and needs change, the way you approach the world has to change with them. So follow your whims! Don't force yourself to be who you think you might be.

i have this theory that who you are today, isn't exactly who you were yesterday. i believe this (to some extent) because i don't believe in time as something that goes on and on, but rather something that has already ran its course, and if you could look along time, you would see that the you that you were when you were, say...12 years old, still exist, right now. You only feel like you've grown up from that stage because we can't perceive time on that level (don't worry, i'm confused too!).Anyway, what this means is that every day is a new day of evolution. The you that is 80 years old already exist, you simply need to progress to that point. So your always progressing! Even in your depressed days of feeling like you're going nowhere in life, you are actually progressing towards some greater version of yourself; you simply don't understand because you can't perceive such a level of evolution, not with the limitations of this flesh.

great answer Livvy. thanks. so m gonna go ahead n let d world define me instead of me being confined.

So, Personality is the particular combination of emotional, attitudinal, and behavioral response patterns of an individual. Personality does change. With every experience that happens in your life, every people you met. Your view and perceptions on on such situations/things changes as time goes. And there's different personality types. You can have a little bit of each. You might think that you're always changing. Some attitudes does stay with you, or are pretty dominant. But your personality makes you who you are, whatever happens. So don't worry. :)
