I’ll be turning 31 years old and I’m kind of feeling that I’m not doing nothing with my money. I’m a software engineer living in Germany and earning around 3300 USD net monthly. In my bank account I have around 67,000 USD and I don’t have too much expenses. I don’t earn a house/apartment, don’t have kids and no wife… I don’t even have a car… Public transportation is just fine for me (Germany has a good public transportation system)

Where I really like to spend my money is on trips around the world and that’s it. I live with my girlfriend paying around 320€ monthly. I get food at the company for around 3,50€

My only investments at the moment are:

1) When I was 26 y/o I invested 7000€ in a photovoltaic plant and for that I’m getting around 1000€ for the next 16 years.

2) At the company where I’m working at they offer cheap shares so I also invested some money on that, nothing fancy.

How would you wish you had invested your money if you were 30 again?

What would you do if you where in my position?

Thanks for the financial help!
