You will Go Nowhere if you do not want to go Anywhere.

Once the business is stabilized, we lose the focus on growing the business. Most of the things get streamlined and then complacency creeps in. Everything becomes routine. If you are looking to grow constantly then mere routine will not help. You need to do one exercise. 

The exercise is Goal Setting Exercise. If you hit the road and do not decide where to go, you will not reach anywhere. You will just roam around. But if you decide that you want to go to certain place, you will do anything to get there. Even if you cannot find a way, you will make one. You will have the mission to reach there and your every step will be towards that Goal. Whenever you set Goal, you find the energy to jump over obstacles and reach your goal.

Whenever you set a goal, you should also do the back calculations. Say, if you decide that you want to go from 10 units to 12 units in 12 months then what should you do. Would your current portfolio of products take you there? Would your current portfolio of clients allow you to grow to that level? Do you need to add machines or services, etc. 

Decide your goal now and grow at the speed that you want.

I have one good video explaining Goal Setting.
