Believe it or not, a lot stress can always be prevented with careful organization and planning.
Do not wait until the last minute. The most stressful moments come when you try to do things in a rush. Write a work plan for your projects. Create mini-deadlines for smaller tasks.
Work on those small tasks diligently and you’ll find yourself finishing your project without even breaking a sweat.
Ask for help. It is not a sign of weakness to ask for help if you’re in a pinch. It only goes to show your ability to assess situations and knowing how to handle them. You can see the use of manpower as this.
Take a break. There is nothing wrong in taking a break. Resting a bit and taking your mind off the craziness of work can give you fresh perspective when you get back to your task. So relax. Better yet, sleep on it. Let your mind rest and recharge.
