I think anything is possible if you have the mindset and the will and desire to do it and put the time in.
With self-discipline most anything is possible.
If people take anything from my music, it should be motivation to know that anything is possible as long as you keep working at it and don't back down.
The optimist underestimates how difficult it is to achieve real change, believing that anything is possible and it's possible now. Only by confronting head-on the reality that all progress is going to be obstructed by vested interests and corrupted by human venality can we create realistic programmes that actually have a chance of success.
To all the other dreamers out there, don't ever stop or let the world's negativity disenchant you or your spirit. If you surround yourself with love and the right people, anything is possible.
