Surrounding yourself with like-minds is a great place to start to find a comparable significant other... What hobby/event do you love?
Get away from the office or away from a situation that brings you stress and take a moment for yourself. Listen to your mind and body and allow yourself to take time to regroup and recharge regularly.
Look for ways to increase your steps every day. Every step you take is one step closer to a healthier heart and better livelihood.
