Why, oh why

What is a question that you often find yourself asking?
I have always and constantly been asking myself the question of, "Is this all worth it?"  I have always wondered if all these works that i have been doing or the things i will be doing worth doing. Should i study in school everyday and study SAT when i don't need them in the future? should i go to college while the economy is so bad? Often times lately i find myself being so paranoid about the future and now.
Right now, a lot of the things that i am going through and paying all my effort and time too are not getting anything back. I spent all this time drawing and painting, despite the fact that i like it, however my mom and dad just feels, eh. I spent so much time on reading and reading and learning new things, but when it comes to the eyes of my parents, it just feels the same, eh. I feel as if nothing i do right now is worth it. I may like it, but  i wished that i could get some approval, even if a little. Since my childhood, i have been actively participating in all kinds of things from sports to clubs. To me, i find that my wide interest and proficiency in taekwando and swimming as where my pride lies, however to my parents they seems to be just normal. It is not until recently where i realized that i have been constantly trying to gain approval of my parents, but it seems to me none worked. For this reason, i begin to start questioning more and more things if it is worth it. this small question and self boost turn all my future thinking into dust. The question might be a simple thing, but it evolved into a big part of my mind. I became constantly worried that i might not be doing enough or my skills or knowledge isn't sufficient enough. Is this all worth it? is what i am doing now worth it if i think is pretty bad? It got me questioning everything.
