Wherever you may go or stay you will always look for a place that you will feel "HOME".
The latter part is true.
Whenever you are and whatever you life are living, you'll still have that one special place in your heart and that's what you wanna call home. Regardless of how good you are as an investor or a realtor, still, you'll have that place where you just want to stay and have a good day.
And for the young ones, if they're capable of having a home, do not hesitate and evaluate yourselves and get a home while you're still young.
