The two are very much related. Doing what you say you will do is probably one of the most crucial factors in building trust. An acquaintance has the opposite habit of committing to something, and then either not follow through, or cancel at the last minute. I know people aren’t perfect, and don’t pass judgment based on an incidence. But after a pattern developed, I knew that I couldn’t trust that person anymore.
Sometimes people agree to commitments simply to avoid a conflict. But eventually but following through, they destroy their own credibility. So it’s better to say no upfront, and set the proper expectation. It requires a bit of courage, but at least trust and reputation won’t be shattered down the road.
I’m not only referring to that activity in the bedroom. 
But also in many other area of life, exercise builds endurance and energy. It helps to get over the dreadful rut. The hardest part is often the beginning. Once you get into a flow, it’s much easier to get things done.
The obvious effect is that you also get fit physically, become more attractive, and gain energy. Surprisingly your mind becomes sharper too possibly with the increased blood circulation to the brain. One Alzheimer study actually listed regular exercise as a top prevention method against becoming a mindless vegetable.
One big reason people give against exercise is laziness and complacency. For decades, I felt the same whenever it comes to jogging. I know doing it regularly is good for me. But somehow I just never kept at it regularly. But last December I decided to be more consistent and begin to jog, a lot whole lot, but at least once a week. So far I’m averaging about 20 miles per month. I like to get it up to 30. I’ve also found that once I get started, I really enjoy the feeling afterwards. It’s like a drug that produces a natural high.
So start exercising and start reaping the benefits!
Time magazine published an article in March suggesting that Type A people, tend to have more children (11% more for males, and 19% for females) than their more passive peers. Looks like another piece of the evolutionary puzzle that explains why certain behaviors such as leadership and decisiveness are considered sexier & more desirable. Here’s another reason to be an Alpha Male or Female, leave more decedents. The meek will not likely inherit the earth. Instead they’ll be outnumbered & out bred by the aggressive.
My name is kind of like John Smith, just too damn common! Put it in Google, and you get a lot of people who aren’t me! It kind of bugs me, because unlike most Americans, I had an opportunity to choose my first name after I came to US as a kid. Should have given it more thought instead of just plucking one out the thin air. If I could do it over again, I go with something with more memorable, maybe “Kronos,” after the Greek Mythology. That’ sound like a powerful & masculine name. Or at the risk of sounding like a high school Mascot, I could just add a nick name, Andrew “the Titan” Wang.
