One tip I can offer you guys is .. Cold Showers!!
They are hard to get used to, and some people don't have the determination or balls to have them, but I guarantee if you wake up and go straight into a cold shower, you will be more productive! It doesn't matter if you only had 3 hours sleep, if you dive into an icy cold shower, you will wake the f**k up! haha
They make you feel 'alive' and ready to start your day! I have one every single morning, and I am healthier than I have ever been.
If you find yourself sluggish when you wake up, have a cold shower and it will increase your productivity, ten fold. Not to mention they have loads of other benefits too .. Google it
