Don't start smoking weed, don't take any drugs. They are only a hindrance to you're path of growth and I've been through some of the worst times of my life because of them. Smoking weed, yeah it "chills you out and you can think deeper" but after that hour is over, it has the opposite effect that's lasts longer in the times when you're actually living your truthful experience without any intoxicants. Weed speeds up the mind, which in turn leads you to wanting to slow the mind down, so you smoke more and more until it no longer servers you're chaotic mind which is when you then turn to harder drugs.
I totalllllllllllllllllllllllllllllllllllllly understand where you're coming from. You're looking for a deeper meaning to life then the current experience that everyone is after, gaining money. Because what reason do we gain money? It's so we can buy things we want, which in turn make us happy. Why do they make us happy? Because we feel happiness inside when we receive an object of our desire. Why do we feel happiness inside? Because we create it within our own body. A dead material object or a bank digit on a screen doesn't make us happy, we create the happiness in reaction to it.
This is what lead me to spirituality, to gain control over our emotions and for a deeper meaning to life. I for one am sick of how the majority of people haven't got a clue as to why they are doing what they are doing, they are simply plodding along with not even the slightest thought about what they are really doing. Gaining money, getting wasted on drugs/alcohol, work, repeat.
I lost most of my passion for things, i am in the same situation as you, not sure which direction to direct my energy. Health is what I've now taken an interest in. I can't say it's gripped me by the balls and it's my new passion, like some things have in the past, but it's nice to know that instead of my health declining over time like most people, it's actually getting better and i can only have a positive outlook on the future of my health.
So, perhaps health and spirituality could be an option for you to research into, you know, something that is essential to life as we know it and where you can experience a better future. Health is wealth ^^
Don't want this to be a debate but the effect of weed is completely user dependent - I've smoked weed for 5 years now haven't stopped once I still get high and no it doesn't make you want 'hard drugs' that's one of the most idiotic arguments against weed and has been disprove thousands of times. I believe weed will help you, asses yourself - as your ego doesn't affect you when you are high, and our ego's are what drives our self perception eliminate the ego - see yourself for you who you are.
Also spirituality is illogical. The better alternative is philosophy
