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.
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.
You've phrased it in a bit of an unusual way, people generally don't close successful businesses - they'd end up selling them off and may choose to pursue a different line of business instead which may turn out to be a poor swap. It sounds a bit like "the grass is always greener on the other side" and people chasing a dream that might not be true. However some people quite simply get burned out and bored after doing one thing for a long enough time, so even if they ended up losing on a new venture, the break in monotony might be better for their health in one way. People who have built really successful businesses can ultimately choose to hand over the management to members of staff instead, another hole in the logic you've put forward.
