Lots of people walk the camino in search of something more meaningful, in line perhaps with the sentiments well expressed by Michael, but I believe our individual personalities and circumstances mean there is a distinct difference between looking for something more rewarding on the basis of placing a bet and taking a chance, being in a position, such as redundancy or a business sale, where we may have (the potentially beneficial opportunity) to confront drastic change, and balancing what degree of change we can actually manage and deliver relative to our current routine and responsibilities.
We all think we want something different and more meaningful, but what is it and how do we find it. Dropping our current life like a heavy suitcase and just leaving it behind is a good metaphor, but one detached from both the practicalities of everyday life and the potential solution itself. Just abandoning a well paid career on the back of a rash decision is not really a bona fide solution without proper consideration of the outcome or the alternatives unless that decision is the only way of imposing the need for drastic change upon yourself.
The camino appears to have been endowed with the ability to provide 'a solution', possibly in relation to it's original heritage as a pilgrim route, the time it provides en route for personal contemplation, and because of its international renown, the sheer volume of walkers that offers the opportunity to interact with different people from different cultures. But make no mistake, walking the camino will still only be swapping one routine for another, but in a context that separates us temporarily from the responsibilities, pressures and decisions of our everyday life. If it's time to think that you feel you need, does it have to be the camino, does it have to be the camino now, or will another trail in your own country provide a suitable detachment and environment.
The happiness in our life is really a function of our relationships, family, work, friends, and are we going to be happier in a different shade of the same thing somewhere else. Possibly, but always and only if we have addressed the need for change within ourselves. If we can't address that need and that issue, then all other external changes are unlikely to prove successful in providing that more meaningful 'solution'.
Specifically, if you can have 5 consecutive days of leave and Labor Day is a Monday, can't you be away for a total of 9 days including the two weekends either side; use this time to do your camino walk, take the time to think and determine whether you want to come back and do more next time, possibly by asking for a sabbatical or longer unpaid leave - more companies are open to this these days and understand the benefits to them of their employees taking a career break and recharging the batteries.
