Being passionate about helping others and remain on top of new technologies and trends is a great gift that makes the time pass even quicker. While doing this is quite easy to forget oneself. Aim to have adequate breaks and stay healthy. Balance is the key to a great person and professional.
Having hobbies is a great way to reward yourself and have a chance to recharge your creativity and passion. Working hard is not always the best approach. Some opportunities are best when not taken.
Always provide the best advice you can give even if this may not be what the person wants to hear. Be objective and fair at all times. Understand the customer to better solve their issues.
