What is the deciding factor for relative importance in your life? For most people it is their values. Deciding what is important is an ever-shifting game you play in your head.
Do you remember what was important when you were three days old? Perhaps it was food, warmth and comfort. But when you were eight, 16 and 21, what you prioritised may have been different. I am almost certain that it would have been.
What is valued by a 30 year old is unlikely to be the same as that valued by an 80 year old. Time, location, wealth, health, education and family will all have an impact on what you think is valuable. In addition, what you value can shift as your life shifts or with new information. It is inevitable.
A good way to discover what is truly important to you, is to check how you spend your time. If you spend your time at the pub with friends, family may not be as high on your list as you thought. However, working everyday to bring in the income, so your family can be fed and safe, may take precedence over spending time with them.
Deciding what is important can be tricky and have many layers.
