When does persistence become irrational? 

But if they think you've been persistent then you'll be using the competitions marketing as leverage!"

But if you are persistent and determined to put in the time, effort, marketing and treat it as a business, you can most definitely make it happen.

I hope it's true and you stay persistent, real estate can be very lucrative.Hope also to see you more around the forums!

Good to see someone your age being this ambitious, if you stay focused and persistent then you will definitely go places!!

Only to essentially give up because I did not get immediate results.Don't be me.Consistence and persistence.

Regardless of what anyone says, starting a new business takes risk, courage and persistence, and as @Andrew Holmes shared, that's why so few are successful at it.  

There will be always ups and downs in the investment.The only thing that separates a successful ones and a normal ones are PERSISTENCE (some called it grit).Just believe in whatever you are doing now and it will eventually lead you to your goals.

Be persistant and don't let them get away with any screwing around.

I believe in persistence above all else.
