What!! Hold a stock for 5 to 7 years?

I see 2 ways to grow wealth:

• Invest in a portfolio that you never sell because they are the companies that can increase shareholders' value over many decades.  Unfortunately, I cannot identify such companies.
  

Microsoft? Berkshire? I have a ex-colleague who was investing for the first time. He took a while and finally decided to dump all his $ into Berkshire in 2009 at $70k a share. $70k is a lot considering he has worked for only ~3 yrs. I believe he is still holding on to it now.
