Chasing after an illusion is equivalent to chasing nothing.
If you are not satisfied with who you are right now, just learn something new in order to change yourself. Changing oneself or adapting oneself is a goal, and learning is a medium to enact that goal.
If you didn't choose to be something, then choose to change.
Discovering something new doesn't always mean discovery of something unknown. We can discover new ideas by reflecting over what we know already.
Most of our problems arise when we refuse to adapt to change.
The only way to grow is to understand and accept change is common. If you refuse that then you'll only be taking away your learning opportunities.
We all are somehow resistant to change. No matter how small or big. Yet when the change happens, we find a way to adapt.
Your flaws are like traps in your journey of life. If you tackle them head on you'll get stuck, at times wounded. But if you plan carefully their discovery and destruction, you'll be able to fill the gaps those traps leave behind with your determination.
