The best vitamin on the market is NOT a vitamin. It is your own self control to make better choices in what you eat daily and how you fuel your engine. You have to take the time to research a bit. You don't just go and buy a car or house without doing a little bit of due diligence now do you? All of the vitamins you require are at your local market/grocery store. You just have to figure out which is which and how to balance them. After a divorce 9 years ago (with shared custody of 2 young kids) & deciding to quit my job to join the ranks of entrepreneurs - I let myself go quite a bit while playing the 'I'm too busy' card. Only after about 5 years did I discover what worked for me. Surrounding yourself with like minds certainly helps - but the catalyst has to be yourself. I made the commitment to exercise 3x per week and look hard at what crap I was putting in my body. That was a start. In the past year - I have had major lower back neurosurgery, joined Crossfit with my wife and eat cleaner (and much better tasting food) than ever in my life. I'm 45, lost 30 pounds and can hold my own cardio/ strength/ endurance with most 25 year olds. (And still enjoy some cold pints when I want !) So - it's YOU that has to make the call. If my lazy ass can go through what I have and feel this great about everything in life - YOU can as well. Vitamins - only a very small tool that will allow you to drop a grand a year - but maybe no benefit if you don't complete the package. Managing some 'TOUGH SHIT' in your life/work ? Maybe I can help.....I've seen almost all of it the past few years and have come out pretty unscathed !
