As a selfemployed artist for me it will all come down to self-discipline. I think of noone you can expect to act disciplined without motivation. And motivation is a very hard word.
You have to feel like you are taking away all the bad in the world. If you don’t feel this then there is no motivation, just you dulling in in practical, logical, rational answers. You have to feel you’re work is GOOD!
First of all I do a lot of sports to get feeling high and to feel like doing things. I can sit and be undisciplined for a whole day or I can grab a bike and cycle for hours on an end. Nothing will get you down faster than living in doubt because you need to act self-disciplined, but lack the motivation.
So I take long rides on my bike or do exercises with my dumbbells with little weight, so I last long. This clears my mind and gets me motivated.
But motivation can also be a psychological thing. You need to know what drives you. For me it is the fight against a system that tried to keep me small. The only way out is self-discipline for me, because if you can’t expect nothing more from the power of the society around you, you have got to turn to yourself!
And this is a hard step, turning towards yourself. Putting away all shame and trust on your own capabilities. Sometimes it might even be a little on the egoistic side to take power in own hands. But eventually this will be the only way to come to the best ideas and works for your own life, because you are the only one who has got to live it and sees how to.
So take action. Go sporting and feel alive. From that basis take care of yourself and this world!
