Encourage your candidate to hold on a little longer when he feels like giving up. Try and find a possibility together to attain a set goal. Encourage the candidate to prepare well against resistance or complications from others.
Investigate a recent situation with your candidate in which he had to and actually did achieve a goal despite adversity and resistance from others. What was the candidate’s attitude? What was the reason for success?
Ask your candidate to write down reasons that help attaining a certain goal and reasons that get in the way. Encourage him to find a way to deal with hindering reasons constructively.
Practise defining goals in a SMART (Specific, Measurable, Attainable, Realistic, Timely) way with your candidate.
