Please, try to eat a bit less meat, a bit more veggies from today. Let it become a habit gradually until not to eat meat anymore. Then, observe the changing of the body and spirit after eating veggies, fruits and grains.
If you develop a pure and sincere motivation, if you are motivated by a wish to help on the basis of kindness, compassion, and respect, then you can carry on any kind of work, in any field, and function more effectively.
Peace starts within each one of us. When we have inner peace, we can be at peace with those around us. When our community is in a state of peace, it can share peace with neighboring communities, and so on. When we feel love and kindness towards others, it not only makes others feel loved and cared for, but it helps us also to develop inner happiness and peace.
