Productivity is something that we define for ourselves. Some ways to manage time effectively are;
1.Try to organise your time and make a schedule: Having a routine can be instrumental in getting maximum done in minimum time.
2. Block time for important tasks: schedule the most important task for the time when you are the most productive.
3. Take a digital break: Stay away from digital spaces and gadgets for at least some time every day in order to minimise distractions and complete your tasks with focus.
4. Effectively Prioritise: Without prioritising you may find yourself stranded. Prioritise your tasks as per the importance of each task and eliminate the distracting elements.
5. Avoid switching between tasks: While multitasking may seem lucrative, there’s not necessarily more that you are getting done. Allow yourself to truly focus on one task and then move on to the next.

You can actually do number 3 with making an easy decision and seeing it through. Always try to give social media some space, as they are a beautiful source of distraction

Good points but what about those that make money through number 3?... It depends on you and your readiness to make things work.

Only if your phone is a source of hustle to you and not a source of distraction. I believe you get what I mean?
