I am 28 years old and graduated from a good stem degree. I have a GF and an extremely stressful job that I hate. I hate to spend more money now that I have my gf, but the validation and warmth that she can give reliefs sometimes a bit stress...

So my plan is the following: I will ditch my GF in some weeks, work for another 6 months and as soon as I have saved 15.000€ I will just live for one year in a south east Asia. I am a programmer and have a side business that generates me roughly 1k€ per month if I work 20h a week. With that amount of work I am completely happy and I can life a chilled life in different countries while travelling...and if I don't want to work, I could actually just do nothing at all...

Are there any flaws in my thinking ?
