These are extremely important tips that you give my good friend and I think that in a way sit you have become an expert in finance, at least the experience allows you to speak properly about it. It is essential what you mention about ending debts and making a budget of expenses, especially not to acquire more debts than you already had initially, I think that even in the midst of a crazy economy like the current one in many countries if you can generate the space to be financially independent, we must only have a good plan. Thanks for sharing your good advice as always.
Note: You should not sacrifice everything, I think you should give importance to each thing and the value it has and only do without what does not contribute to your life, otherwise you end up sick. Of course that is my opinion.
