As a digital nomad, one enjoys the freedom to work from anywhere and everywhere.
One would be free to accept any work that comes across during travel and as every work comes with a deadline, a digital nomad needs to be careful of the digital nomad jobs where he/she should be selecting the work requirements before accepting the offer.
As a digital nomad, you are unsure where you will be the next day hence accepting assignment with tight deadlines is not a viable choice.
It is better to pre-calculate the work which you currently have and then accept new work. Although one would be confident that the work will be completed in stipulated time additional factors can hamper this and you should keep at least ± 3 days as grace period.
Accept any work which has a minimum of 2 weeks of deadline, again it depends on the country which you are at as some places have bad network connections, some has very good connections.
If the work that has come across is your forte then there are no qualms that you should reject it. However, as a digital nomad you would not have a proper office and also, the brand/organization will be dependent on you hence, considering many things in mind take a proper decision.
