You are not alone.
Whether it be the blues of starting a brand or the monotony of going to work everyday or the repetitiveness of studying for an exam you have next week, you're not alone. There is days where I wake up and don't feel like doing anything, there's days where I wake up and want to take on the world. No matter what I always have in the back of my head the goals I want to achieve and what I do everyday gets me one step closer to my goals. Even if it's a baby step, it's still forward.
Have a goal in mind of something you want to achieve, it will give you a sense of purpose everyday and something to work towards. Once you've achieved it move onto the next thing. I'm not saying you have to have a goal to work towards or any goals at all but it does help with feeling a great sense of purpose and direction in life.
Dream so big that it scares you. Reach for the stars so if you fall, you land on a cloud. As hard as it is, try not to talk about it too much so you can stay focused and head strong when working towards your goal. If you're too busy talking about your goals when are you going to have time to work towards them?
Anyway back to the main topic, we are all going through the similar issues, problems and roadblocks, if you can just hang in there and keep moving forward you will thank yourself and you'll honestly laugh at how far you have come. Don't ever give up and keep working hard/smart. I don't always like saying never give up but if you really think about it and break the words down you can find the strength to truly smash your goals.
