Stuck in a rut with your career? It’s a common problem – many workers find themselves in a job they find unchallenging, but lack the means to climb further up the career ladder. One way to improve your job prospects is to learn a new skill. Most people have busy lives outside of work, and don’t necessarily have spare time to devote to learning. However, there is an untapped source of free time in the working day – the lunch break. The most successful business people use their breaks for self-improvement. An hour might not sound much, but if you study a new skill for an hour every day, the time soon adds up into something significant.
