It is possible to start a part-time business when you are still working at a job, in fact sometimes the bankers prefer this! People have different energy levels and abilities, but you will give yourself the best chance of succeeding if you are fully committed to the endeavor.
It is not the right time to start a business if you are already experiencing turmoil or stress in your life. If your personal life is in flux (new marriage, new baby, in the middle of a divorce) or if you have other demands on your time and attention (family health issues) it is smart to put off starting your business until your life is more in control.
The perfect time to start a business is not related to age; many successful owners are very young while others are mature and experienced. It is really a matter of where you are in your life and whether you are ready for the challenge.
