I've found that if one is to overcome one's shortcomings , one needs to view them as temporary. Music , atleast for me (I'm sure most musicians feels the same way), with all aspects involved , is a learning process , and I find it more difficult to learn something when I have a negative wibe towards what I am trying to master , that goes for anything.
I have only serious affection for my instrument , and I feel I can't allow myself to have any negativeness involved with that.
When I feel I get frustrated over some part or technique I'm trying to learn , I just sit down and analyze what I am doing , and I go through what I'm doing at a slow pace , learn to walk before you run.
The basic ingredients in my way of learning is patience , focus , discipline and fun , these four ingredients are closely knitted together.
I am my own teacher , I've never had any instruction or classes , what I learn , I learn by myself. Teach yourself as you would teach your most promising pupil.
Though I am perfectly aware of my shortcomings , I still feel happy and secure about it because of their relative short 'life'.
Problems? Negativeness is only selfinflicted punishment , it will get you nowhere.
