Better to ask for forgiveness, rather than ask for permission.
People who have the capabilities and responsibility to get things done are invariably slowed down or even severely handicapped by people who retain all authority and control resources.
Visualise a typical organisational problem.
It is very important for you to get something done urgently. You ask for permission to higher authorities to act. Dithering takes place and either no decision is given to you or you are not allowed to proceed. You are responsible and you see the situation deteriorating rapidly and you feel compelled to do something. What do you do?
Basically there are three options
1. Do nothing
2. Hold fort and plead once again for permission
3. Act without permission.
Only option 3 will probably deliver results. The decisive, action oriented person acts. If results are favourable and the objectives met, then one is contented, and successful. The worst that can happen is some sensitive bureaucrat's ego would have been bruised and this can usually be tackled later.
Timing is crucial for any endeavour.
Remember it is easier to beg for forgiveness than to ask for permission
If successful, there is a good chance for a reward, but if the endeavour fails it might be a good time to review career options or write a book.
