1)Stop stewing and start doing. Take the time you spend procrastinating and complaining and put it toward something positive that will improve your business.
2) Be a little nicer than you have to be: this goes for clients and colleagues alike.
3) Become too busy to work for clients who pay you poorly or treat you badly. Instead of complaining about them, market yourself consistently and you won’t need them anymore.
4) See yourself as a professional and be willing to invest time and money in your business. This includes conferences, training, technology, etc.
