For those people who seem to have a lot of responsibility on their shoulders, this lesson can come or better said they might learn it rather late in life. They spend so much on others till there's none left for them. If you're among those kind, you really should learn this lesson.
To some people, you spending on yourself is too much and not necessary, but fuck it if you've put in the work, worked your ass off, then you really should spoil and pamper yourself once in a while. Learn this lesson of treating yourself, no one will take care of you like you.
Life is hard, and add that to the fact that life is also short. So once in a while you really need to tell yourself fuck it and spend on yourself. So long as you don't do that to your detriment financially, do pamper yourselves. Get yourself that expensive watch or shoe or dress or bag you've always wanted, take yourself out and eat what you want. Just freaking have fun, life like I've been saying is short.
Keep putting in the work my friends, and as you do so never forget to once in a while also tell yourself fuck it and go spoil yourself. Life is too short to live a boring life.
