Don't try to make sense of life; it makes sense of you... Don't try to understand what the point is, live in it instead.
By not questioning it. Don't question the purpose in life unless the situation is correct. Thinking that because you cannot see a purpose, that there is none, is a very assumptious way of seeing things. Live how you feel you should live, express yourself how you feel you should express yourself; your purpose in life will be realized somewhere along the line.
