Situations at work demand leaders of various sizes and capabilities. Most of them need ones without leadership titles. They need people who make a difference, then and there. Those who contribute in these situations go-a-long-way with the company and people who benefited.
It is not opportunism. It is genuine interest to be part of the company and its need is what counts. Pure-play opportunistic pursuits become easily visible to everyone around. Genuine efforts yield better results and garner peer-support. It is a nice feeling to be wanted, at work. This sets you free and puts you in an orbit of being at the right place. A dream-job-zone. Raise your hand where there’s a need. Build small wins and set yourself free, at work!
