Every time you enter your primary place of work, make it an integral habit to actively say good morning to everyone.
It’s a tiny act that done over Lo periods of time can have a massive impact.
It could be in the office or in the factory or even the job site, learn to appreciate your colleagues regardless of if they respond or not.
It’s the point and habit of actively recognising the people you spend, on average, the most time with.
Unexpected things come from small repeated efforts.
