Hello friend excellent publication, the truth you are very right in all the advice you give, I think we can not have all the eggs in one basket, we must learn to diversify income because if we lose some we have the rest available. With respect to expenses most people don't worry about a future and just want to spend everything they earn, but the ideal would be to keep a percentage of your monthly salary or invest it in something that generates another extra income.
I like your comment, "invest it in something that generates another extra income." Not only can we work for money, but also have our money work for us.
Thank you very much for you kind comments @franyeligonzalez.
