Take your time,but finish one task instead of jumping on ten different tasks and not completing any.
It feels good when you are managing multiple tasks, as you feel a lot of things are started. In reality, you are loosing confidence and focus as you don’t see any task reaching to the completion.
Take one task, finish it with focus and with speed. Then move on to the next one. This is how you complete a lot of tasks over the period of time with peace of mind and better results.
