We might not feel the importance of it until we have been lay off from the job.
I have a question for those working for an entity or government, if you are being sacked today, what will be your faith? Will you still be financially strong, can your other sources of income keeps you going or you will be devastated by the loss of your job.
In this current economy, it's suicidal to have only one source of income.
If you must live well you must be ready to grab the bull by his horn am make life changing decisions by having more than one source of income.
Don't put your financial destiny in the hands of your bosses, you might not know the importance of having your own business till you have been sacked. think about it.
I would add - wherever you work - always create an alternative income option. From your personal business, to investments ! Always keep in mind that there are a lot of risks, with a probability higher than 0, that you will be left without your current job. It can be anything - problems in business, global changes, corruption, natural disasters. And having no alternative source of income, you may wake up one fine morning and realize that now you have NO income, if you have not prepared a "reserve airfield" in advance. And it will be very painful to realize.... ALWAYS create at least 1 spare income channel, MINIMUM 1 spare, but more is better
