Read The Richest Man in Babylon
Read The Richest Man in Babylon by George S. Clason (1926) first to get an understanding on basic saving principles. Anything after should be based on said principles.
In the book, the author writes exactly about wealth growth. It's written in the form of parables or stories taking place in the ancient city of Babylon so it's really easy reading.
The main points to take away are as follows:
Seven Cures For a Lean Purse
- Save 10% of your income.
- Control your expenditures by making a drawing a firm line between necessities and wants.
- Invest your savings so that they grow on their own.
- Do not be tempted by promises of quick returns, instead ensure that risks are not too high.
- Own your own house.
- Prepare future sources of income for when you are old.
- Learn more continuously, such that your income grows.
as well as
The Five Laws of Gold
- Save 10% of your income.
- Invest your savings so that they grow on their own.
- Be patient in investment and avoid undue risk.
- Seek advice from industry experts on investments you are considering.
- Do not participate in get-rich-quick schemes and do not project your greed into false optimism.
There are several other parables and you might find some of the lessons to be repetitive, but that is mainly because this was published back in the day as pamphlets that were distributed by banks and insurance companies in the United States before they were compiled into a book.

After that, create a portfolio
I can't really give advice that is specific to Colombia, but basically you should divide your savings by risk category. As you are young, you should aim for a portfolio which leans more towards risk than otherwise.
A good breakdown may be as such:
40% - High risk, e.g., penny stocks, hedge funds. Essentially high risk with high returns.
40% - Medium risk, e.g., stocks, bonds, real estate, mutual trust funds. Higher risk than bank savings, higher returns than bank savings.
20% - Low risk, e.g., government bonds, fixed deposits. Low risk, low returns
This spread may shift over time in line with your risk appetite which generally shifts towards lower risk as you get older and your responsibilities increase.
Other considerations
Invest in yourself to learn new skills to increase your earning potential.
If a family member or a friend wants to start a business and can display great business acumen and has a great business idea, get second and third opinions on the idea, and check and double-check that you'll be able to get returns. If you're satisfied, go ahead and invest/loan them the money.
Probably don't spend it all in one place on things you want.
