Success in any field requires a lot of effort.But special points for Practice :
1) Go for the practise if you have the links ( in real sense it means if ur dad/father in law has the links ).
2) Go for the practise if you have relatives, friends who are industrialists,IAS officers.
3) Go for the practise if you have connections with top bankers.
Even if u hav above links,there is no guarantee that they will help you because in corporate world nobody wants to change their CA in normal circumstances( evryone know the obvious reasons) but they may provide you some opportunity. Avail that opportunity to the best.
Have patience.Learn continuously.Spend 5 years in practise and people will come to you.Success, fame, money will come after considerable time period, But if you do hardwork everything will come later or sooner.
Practice is like a startup. You will give your best but you may not achieve your professional goals. With Financial Freedom, you have to manage the risks.
Consider above factors if you wanna go for the practise.
