What's the best way to increase productivity?

Define what you want to achieve. Breaking down your main goal into sub-goals or tasks can make it more manageable. Determine which tasks are most important and tackle those first. The Eisenhower Box (also known as the Urgent-Important Matrix) can be helpful in this regard. and your time management is really important.

I think setting up goals for yourself is very helpful. I also did that during studies - when I knew I have to go through certain amount of chapters in a day in order to be able to know everything for the exam day and not being overloaded with work I was just productive enough to do what I planned. You are also way more productive when you are well rested and in the right headspace so taking care of that is super important :)

By counting to 3 and just diving into what needs to be done. Baby steps compound and momentum kicks in. That's when one would stop asking "best way to increase productivity", because you know now you're it. It's hard, of course, but most things worth doing and achieving are. Good luck

I find it helpful to implement artificial deadlines - usually followed by something that is like a reward. 'I have to get this done by lunch!' for example. Makes me focus on the task, with a reward to aim for

Prioritize tasks, minimize distractions, and delegate effectively.

Listen to customers' voices (without ever pandering) and repeatedly make improvements.

Plan your activities and strictly follow the plan, and also do not forget to switch and relax.

I try not to plan too many things for a day/week etc. When I have a lot on my plate, I end up feeling frustrated because of an "unproductive day". It's very discouraging. So, no more than one major task for a day, if possible.

Eat the frog first and let the day flow smoother :)
