You don't really need to go the 360 degrees to be successful in life for everything you need is just within you.its not until you also do the same business the next successful person is doing before you gain financial freedom.the part way to success is not fixed you could discover yours.
OP reminds me of some motivational speakers who come up with so many success strategies, meanwhile they are not even successful 
, just kidding. However, I think you have a point that we have great gifts and abilities that we can use to succeed. These abilities are dormant because we have not put them to work or tried to do what we think we can. Copying other people's business or skills is one of the reasons why people fail. It is common to see people establish a business because they see that someone else is succeeding in it. Immediately one persons starts a new business within a few months multiple people have established the same business. You cannot be successful by engaging in a rampant business. We should learn to be creative and innovative if we want to run a successful venture.

Some persons close their long term built businesses to sought for a bigger one and end up losing both instead of making the one they are well acquainted with larger and better.
Stop crossing other people's lane and stop looking outwardly for everything we ever needed is just within.
Opportunities are all around us but it's left for us to see it as an opportunity and make use of it. One good step that is proportional to one good opportunity could lift one to a greater height. just look around, the solutions to your problems are just lying by the corner.
It is only people who are greedy or discontent that would want to do everything they see others do. If you are good in just one business people will patronize you. It is not bad to diversify into other businesses but it should be done after a comprehensive analysis and projections. Just be the best you can and have good customer relations, with hard work and dedication, your business will flourish.Stop crossing other people's lane and stop looking outwardly for everything we ever needed is just within.
