Challenge yourself.

Your Art practice or your job will never challenge you long term, you will first be challenged and then become competent and then if you do not continue to challenge yourself, you will grow comfortable and lazy and then begin to complain that your practice does not challenge you any more.
People say that about their jobs, that they are not challenged.
Its a job and if a robot could do it, you would be replaced.

No job will challenge you, its just a job.
You have to challenge yourself.
Challenge yourself to get better, the job will not challenge you to get better.
Everyone is looking for an external force to challenge them and then everything will change.
The only person who can challenge you, is you.
I talk to so many Artists and I tell them what they should do to improve their Art practice and try and challenge them, but so very few can do it.
Many start out motivated to do it but once I am not saying come on do it, they slowly loose motivation.
Motivation will never do it.
Belief in yourself will do it.
If you don't challenge you and discipline you and push you, it will not happen.
Challenge comes when you recognise that you are paid what you are worth and it is your responsibility to make yourself worth more.
It really is up to you, you are responsible to challenge you.
If you want a better life, then you better become better.
