This is all there is, infact you nailed it pretty hard on the head....
It's one thing to take a profound decision yet it's more difficult to implement it especially when one is still around the influence of former life..
Financial Discipline is a very tough decision to make especially in our own sphere, when I see some persons spend money frivolously I doubt the earning process...
In the other hand they believed that because they worked so hard for it they should as well enjoy it to the fullest ...this is because they have very little knowledge of investment and return on earnings cause that money spent could be channelled to earn multiple returns.
Talking about luck I believe very little on it, the fact remains: do what you have to do, there by creating positive energy around you that attracts the right kind of opportunities to you..
Great one Boss
I find it didn't to even spend frivolously and that's because I already know the consequences and how it'll generally affect me. I think everyone in life feels knowledgeable at one point until they begin to make mistakes. I think the earning process is important like you've pointed out.
As per luck. I believe it exists, especially when it's the only element, needed to crown one's effort.
