There is no doubt that every athlete at the Rio Olympics has spent considerable time identifying and working to address their weaknesses, whether these be mental or physical.  I cannot stress enough the importance of doing this kind of analysis on yourself and your business.  What are your personal strengths and weaknesses as the owner of the business?  What skills could you develop within yourself to improve your ability to develop or market your products or better serve your customers?

If your weakness is public speaking then join your local toastmasters group.  For other weaknesses there are many self-help books available on a wide variety of topics which could be suitable for you – from how to develop your value proposition to how to improve your selling skills. 

If a further qualification would improve your capabilities then completing an MBA may be suitable. 

The moral is to make sure you are always doing something to improve yourself.  Olympic athletes are training every day to improve their strength, endurance or technique.  If you are in business then you need to be continuously improving as well.

The usual response to this is 'I don't have enough time' or 'what will that cost'.  The best response to this is 'will you ever have enough time' and if the answer is no then maybe time management is something you should improve on.  Regarding the cost, there is no doubt the initial cost of doing anything will be higher than the cost of doing nothing.  But if you do nothing then you won't improve however if you continuously improve then looking back after five years your weaknesses should be greatly reduced.
