Why is it difficult to pack a bag, turn round and say - see you in a few days?
Worry and uncertainty
Takes time to prepare
Addiction to computers and devices
Fear of not being comfortable
Family and friend responsibilities
None of the above are excuses for inaction. The question is above why you want to do something. Not why you don’t. Knowing what you want is a conscious thought. So, to conclude: the difficulty of inaction is a lack of imagination.
