You can consider other perspectives. You can even prepare for things in advance. However, nothing can make you fully ready for exciting or challenging times. You can truly experience it only when it happens.
For example, a parent or grandparent dying is more impactful than you would think it would be. You know that in theory, we are all going to die. In addition, you’ve had years and sometimes decades to prepare for the moment. But when it happens, it can be quite a shock to the system.
Winning something special or seeing someone special after a long time can also be intense moment. You can guess how you would feel. But, living it is another level.
It’s good you can’t feel the extremes until those unique moments. It saves those very special or intense moments for only when it happens.
