There's no doubt about it: Everyone needs help in business.
If you're good at what you do it's inevitable that there will be people wanting you to do more work for them.
But how hard you're working shouldn't be measured by how many late nights you spend working in the business, or judged by the time of day you're answering business emails.
If you're feeling overwhelmed and a bit stressed by the volume of work you have on your plate, put aside your pride and look for others to bring something to the table.
I start my day by preparing a list of tasks to delegate, so I can then focus on the work I really need to do.
