I managing several projects, sometimes do some work, ex. frontend or ux. I have great clients, they are listen and trust me. At same time I feel, that can relax and do not work day or more. It makes troubles with quality and deadlines, but I say client "Sorry for delay, it is my fault and etc." and client trust me again. I think that I can make this again and again. I don't worry about money, I have enough for living, but I worry that it is small to make big expenses, like buy house or car. If it gets worse, of course I will begin to work better, but I do not want to wait for it.
How I can motivate myself to make more money and increase quality of my services?
