Adventures can be the best investment!
Spend money on experiences instead of things. This has proven to make people happier in the long run. Years down the road, you will remember the trip you took more than the purse you bought.
Experiences could provide you quality time, pleasure, happiness, and even wisdom. And it's even better if you share them with your special ones. It could be difficult at first because of our constant search for material possessions (in fact, you should keep a balance between both of them). But once you'll start enjoying that special thing about experiences as adventures, you certainly won't stop wanting them as something necessary in your life.
Material things are usually transient, but experiences and what they bring with them, remain forever in our memories. This makes up our self-construction, block by block, it builds who we are as people, professionals, family members, friends, and every important aspect of our life.
