Hi,
I have the following problem in poker:
1- When i win and made some good money, im scared to play more and i quit since i will play with scared money (i dont wanna lose what i won).
2- Somedays i dont feel lucky and dont feel like playing and i dont play, bc i feel i will loss.

what can i do to change this behavior?
