When you feel like all the doors have been shut in your face and you have nowhere left to go, keep going. Don't give up. Keep pushing forward. You have to be resilient to make it in this business, so make the most out of every situation you can. Found out a hard/private money lender was a scam? Get out there and find another one. Partnership fell through and now you're left picking up the pieces? Pick them up faster and get back on your feet, find another partner. There's 7.4 billion people out there, you can do it. Don't let failure be the reason why you give up. Remember why you got into this business in the first place...
