I'm stern if anything.. and I take things seriously for the most part. But I also know when to let go and just chill. However I do approach situations according to what they need; I see both "how can I make this in my favor" and "I'll just let it go" depending on what's going on.
However, I don't let things sway me. I used to bend myself to stronger people's will when I was younger and I hated the fact that my integrity was lost. Now I make it a point to stay true to myself, so I do so. I'm not going to fake behaviour around others, and that's how I think it should be. Im generally accepting of others and easygoing that way, but I expect others to do the same to me (as in not being fake) as I wouldn't waste my time with false people.
I have goals I want to reach in life.. and I want to reach them quickly so I rarely like to take things slowly. However when time comes to relax.. I thoroughly enjoy being lazy.
