Why does my mindset keep changing?

Thats how the mind is young one... it ponders back and forth trying to find a solution... since your analytical by nature I assume that you are, that your mind is trying to come to a rational solution... but the emotional bias/resentment that dwells within you is paralyzing your logical side... my advice to you... meditate if you have a hard time trying to cope with your current situation... let your mind relax... once you got the discipline to have a peace of mind and let your logic come naturally... then if your lucky... your will power will increase... your senses heightened... logic comes clearer... intuition perhaps will grow stronger within you... good luck young one... be whole with one's self is the key...
