Gaining trust takes a considerable amount of time. In order to build trust, a person must be reliable. Reliability can be proven with experience. The more reliable a person is, the more trust they gain in the process.
Would a person trust another they never worked with before? Many people have learned through bad experiences, trusting a person they never worked with before is risky.
Surely enough, a person must first earn respect before they can hope to be trusted. Rather then employers or people taking a chance on poor results or missed deadlines, they will look to hire trustworthy people that have a good track record.
Good workers are not always the most reliable ones. There are many good workers that tend to have time management issues. People are not expected to be perfect all the time. Finding time to complete work is mainly a challenge in this day and age.
Scheduling fun time will help a person resolve their time management problems. The next time you find that your time is unaccounted for, be sure to schedule the things you enjoy most to build a rhythm with the processes that create scheduling conflict. Making deadlines is something that is consistent with being reliable, which in result attract respect.
Why is experience necessary to build trust? People that don't have experience lack effective communication skills. These people may have potential to communication, but they need to interact with other people or even engage in a strict work regime to complete assignments. Experience depends on gaining respect, being reliable, and building trust.
It feels good when a person trust you, especially ones that has never met you before, but they know what type of person you are through regular communication. Don't be afraid to go out there and gain experience.
