Take care of what you have now so that it takes care of you in future

In programming there's this policy of "take care of what you have now so that'll take of you tommorow". I've been thinking of it in relation to the PCs or Macs we use no matter how fancy or even if it's not working properly as long as you can write code on it just keep it in best conditions possible in future you'll appreciate it .

Attimes we wanna contemplate on the data subscriptions ,the prices of acquiring some paid courses, attending a bootcamp training among others that will help you master and improve our developer skills but if you choose to focus on what you want to achieve in future you'll just be left complying to the policy of taking care of what you have now so that it takes care of you in future.
