Dare to do only what you can/will be proud of someday. But, desist from doing anything that you might/could regret in the future or for life i.e. think twice and as well apply wisdom on or before you take any decision or make any choice.
Happiness is a matter of choice. Besides, sadness is also a matter of choice. So, which of the above habits or lifestyles have you been or are you indulging in? Anyway, I'm urging you as ever choose happiness rather than sadness. Because, happiness is a good antidote to stress. It equally guarantees and brings longevity. But, the reverse is the case with sadness. Or rather sadness shortens one's life span. Thus, say NO to sadness and then say YES to happiness. For, happiness pays rather than sadness.
I believe everyody in the world should have guns. Citizens should have bazookas and rocket launchers too. I believe that all citizens should have their weapons of choice. However, I also believe that only I should have the ammunition. Because frankly, I wouldn't trust the rest of the goobers with anything more dangerous than string.
I believe the single most significant decision I can make on a day-to-day basis is my choice of attitude. It is more important than my past, my education, my bankroll, my successes or failures, fame or pain, what other people think of me or say about me, my circumstances, or my position. Attitude keeps me going or cripples my progress. It alone fuels my fire or assaults my hope. When my attitudes are right, there is no barrier too high, no valley too deep, no dream too extreme, no challenge too great for me.
