3. Expressing your emotions
A lot of people will go on with their lives by bottling up their emotions. They do this to avoid any sort of problems. Quite often they may not like somebody or have been hurt by a certain person or have held a grudge for so long that they spent their entire life being burden by it. At the end of your life, when you finally let it out or open up to somebody about it, it makes them feel better and they start regretting not doing so earlier. This can be said about having some sort of feeling for a loved one. Maybe you have felt something special towards a person but you never could express it and that can be your biggest regret in life.
